It seems that Nix/Whaley have made a significant number of moves which have generated very positive results.  If our excellent community/staff could pull together a summary of the moves it may prove to be very interesting.  If the NFL goes to an 18 game schedule the ability to make in season moves will become even more important.  I'll get started by listing a few on the O line:  Urbik, Wrotto and Rhinehard.
